To all finito/1t it may concern .1'

Be it known that l. VVILUAM F. EMERSON, a citizen oi' the United States, residing at Buiiialo, in the count); of Erie and State of New York, have invented. new and useful improvements in Grease-Cups. of which the following is a specication.

This invention relates to grease cups for feeding lubricating grease to bearings and consists of a particularly simple and compact means for adapting grease cups for the use therewith of protectively inclosed charges of grease or grease capsules wherein the grease is contained within a paper or other yizontain'er. An important feature of my invention consists in providing an insert for the cup of a form which will permit of its being /inc'fxpensively stamped of sheet metal and which will provide a shoulder positioned to he engaged by the collapsed grease container and will retain the container in exposed position when the cap p0rtion is removed thus greatly facilitating the removal of the emptied container which is held in position permitting of its being pushed ofi without soiling of the hands.

An approved embodiment oi' my present invention is illustrated in the accompanying drawing wherein the reference numerals ofl this description are applied to the 7spending parts in the several views.

corre- Therein Figure l is a vertical sectional view showing a grease cup embodying my invention. Fig. 2 is a similar view showing the parts in advanced position and Fig. 3 is a similar sectional view with the cap removed and Fig. 4 is a plan view ofthe terrule insert.

ig. 5 is a vertical sectional View illustrating my invention embodied in a desirable plunger type of v 'fgrease cup.

ln the embodiment of my invention disclosed in the drawing l indicates the base portion provided with a threaded 'flange portion 2 adapted to be threaded into a suitable bearingrsupport 3 provided with a duct 4 communicating with the bearing or other parts to be lubricated. rlhe base l is provided as shown with a central passage orv outlet 5 for the `lularicant Y communicating with the duct 4 and is also provided on its with threads Aas shown. Upon the threads t there is screwed the grease cup cap adapted to receive a charge ci grease therein and to apply pressure thereon asythe cap is screwed down as inditcated in Fig. 2 to force the grease into the caring. l'n so far as described the parts may be of the usual and standard form of commercial automobile grease cup to which my present invention is particularly applicable.

In accordance with my invention the described type of grease cup is adapted to deliver the lubricant when put up in containers 8 as shown which are desirably of paper and of the-proper size to be received within the cup portion 7 wherein it is placed with the open end 9 toward the' base outlet 5. In operation the cap is then screwed down on the base l and the container collapsed to expel the grease through the outlet 5 into the hearing. l

To permit of successfullyY employing the grease capsules as shown means -o prevent the crushed container adhering to the inside of the cap portion when the cap is removed which as will be readil;T understood would necessitate troublesome manipulation to accomplish its removal. To this end I have devised a simple insert or ferrule 10 of suitable form to be inserted within the base portion 1 and to provide an annular iiange or shoulder 1l spaced from the interior surface of the base in a manner which permits of lthe lower edge of the con tainer being forced-thereunder as ,it is collapsed. The insert 10 is desirably of the flared tubular form as shown which of its being inexpensively stamped up of sheet metal and permits of the passage or the grease therethrough. The lower tubular portion of the insert is designed to hold it firmly in position on the base portion by forcing it into the latter so as vto obtain a frietional hold thereon by'means of the inclined engaging surfaces.

The insert thus provided permits of readily converting the. standard grease cups to be adapted for use with grease capsules and .moreover is equally suitable for handling cations or' my invention can he made withfrom the scop'ethereo and it is therefore intended that all matter con-l out departing permits is advanced hy means of have provided engaged by theA container when collapsed' substantially as described.

2. A grease cup having a base portion provided with an outlet passage for the grease, means for advancing the grease therethrough and a separable insert element adapted to be positioned .Within the base and provided with an annular shoulder adapted to be engaged by a collapsed container substantially as described, 4 'y 3. A grease cup having a base portion provided with an outlet passage for the grease, means for advancmg the grease therethrough and in combination therewitlf means for adapting the same for use with grease Within containers' comprising a tubular insert element having a ared shoulder portion suitably spaced from the wall of the cup to l adapted to be positioned Within the base and toprovide a shoulder to be engaged by the container and' said base and insert element having inclined engaging surfaces for re- ,40

taining the said insert in position substantially as described.

5. An insert element for use in grease cups of standard construction to adapt them for use with grease in collapsible containers, comprising a tubular element having a re= duced` lower portion adapted for frictional holding engagement With the cup and formed at its upper portion with, a shoulder ange spaced from the cup and adapted to be engaged by a collapsed container, substantially as described.

In testimony whereof. I have signed myname to this Specification.
